Hi, I'm hoping someone can help me.
I have a small leak in my GlowWorm 24cxi boiler.
See the photo:


And to help (maybe) I've included a photo of it's rough location:


So water is coming out with a hiss (at some pressure) at the bottom of where that component joins(?) another . I think it's dripping from the cold water supply not the heating circuit as my pressure doesn't drop and the water is cold.
I'm wondering if it's something I can possibly repair? Could I take that component out and reseat it or do i push that metal pin holding it in down further ? [/img]

The clip has not been fitted properly it needs pushing fully home and hopefully it will stop the leak. If not then it may need taking apart and a new o ring fitted.

Just to let you know, I couldn't fix this myself as I didn't have the time or tools. The engineer took the assembly block apart and just replaced it all with new bits. Bloody nightmare really, crap boiler!

To be fair to the boiler ( in this case ) they rarely leak in that position.

The fact that the clip was not correctly fitted usually means that it had been removed before and not put back correctly.

Those "O" ring joints need to be cleaned very carefully and then reassembled using silicone grease.

Appriciate the feedback. I bought the house with a bucket under the boiler, and, as you recommended - it's still there!

I've been told the boiler is only tested to 6? bar of pressure and our water flow can get upto 10bar at night. So I guess that would explain the number of leaks my boiler develops over time. Which is why I'm on British Gas Home Care - just biding my time till it happens again.

If you have such a high overnight pressure you need a pressure reducing valve.

PS: Do you have a water meter? These have a non return valve in them that can cause excessive pressure in a combi causing all manner of leak related grief, a small expansion vessel is needed.

If you have BG plan, why not call them and get the leak sorted?
